WELL-PUMPING POWER.

SPECIFICATION forming part of Letters Patent No. 579,480, dated March23, 1897.

Application filed April 1'7, 1896.

T to whom it may concern.-

Be it known that I, GEORGE WV. GRIMES, of Blufli'ton, in the county ofTells and State of Indiana, have invented new and useful Improvements inWell Pumping Powers, of which the following is a full, clear, and exactdescription.

This invention relates to power devices for operating pump rods orlinesfor either water or oil wells in great numbers from a central station;and the object of the invention is to provide such a power wherein themotion will be uniform and require a minimum of power to operate it.

I will describe a pumping power embodying my invention and then pointout the novel features in the appended claims.

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a plan view of apower embodying myinvention. Fig. 2 is avertical section thereof. Fig. 3 is a plan view of a certainoperating-ring employed. Fig. 4 is a plan view of a pump-line plate.Fig. 5 is a plan View showing another pump-line-plate mechanismemployed. Fig. 6 is a vertical section showing a modification. Fig. 7 isa plan view of a pump-line-actuatin g device carried thereby, and Fig. 8is a plan View of the pump-line plate coacting with the device shown inFig. '7.

Referring to the drawings, 1 designates a base-sill supported ontransverse base-sills 2, 3, and 4, one of which, 3, is arrangedcentrally of thebase-sill 1, and the others are arranged at the endsthereof. Upon the base-sill l is mounted a bed-plate 5, and attached toand extended upwardly from this bed-plate 5 is a fixed post or shaft 6,upon which is mounted to rotate a sleeve 7, having an annular flange atits lower end provided with a groove in which antifriction-balls S arelocated, the said bed-plate 5 being also provided with a groove toreceive said balls.

It will be seen that the interior of the sleeve 7 and the portion of thepost 6 engaged thereby are correspondingly tapered, the wider portion ofsaid taper being at the lower end. Secured rigidly to the sleeve 7 is amastergear 9, meshing with a pinion 10, mounted on a shaft havingbearings in pillow-blocks 11 12, the shaft being provided at its outerend with a band-wheel 13, which may be operated Serial No. 587,988. (Nomodel.)

from any desired source of power, such as an engine or electric motor.

Mounted on the upper side of the mastergear 9 is a ring-plate 14. Thisring-plate 14 is mounted eccentrically to the axis of the master-gear,and it carries on its upper side a pump-line plate 15. The ring-plate 14is designed to rotate relatively to the pumpline plate 15 and to imparta reciprocating motion thereto. To reduce the friction between thepump-line plate and the ring-plate, I provide the pump-line plate withantifriction-rollers adapted to bear against the up wardly-extendedflange portion of the ringplate. In this example of my improvement theantifrictionrollers 16 are mounted on bolts or studs extended downwardfrom the pump-line plate and engaged against the inner periphery of thering-plate.

Above the mechanism just described and rigidly secured to the sleeve? inan eccentric manner is a wheel 17, engaging with its periphery againstpump-rod plates 18 and 19, which have portions 20 engaging,respectively, over the upper and lower surface of the wheel 17 The saidpump-line plates also have inwardly-projecting flanged portions 21 forengaging with the periphery of the wheel 17, and outward of theseflanged portions 21 there is a considerable space between the pump-lineplates to receive the shank portions of coupling-clips, as will behereinafter described.

To the top portion of the post or shaft 6 is attached a metal plate 22,to which the upper ends of brace-rods 23 are bolted, the lower ends ofsaid brace-rods being boltedto the base-sills of the machine. It isobvious that these brace-rods will hold the post or shaft 6 rigidly inan upright position, and, if desired, they may be provided with ordinaryturnbuckles.

For engaging the pump-lines 24 withthe pump-line plate 15 I employclips, here shown as consisting of two longitudinally-separated sections25 26, forming jaws at the outer end to engage with the puinp-lines andhaving at their inner ends clip portions to engage against the upper andlower sides of the pumpline plate. The clips are secured to the pumplineplates so as to swing relatively thereto by means of pins or boltspassing through perforations in the inner clip ends and throughperforations formed vertically in the pumpline plate. The jaw ends ofthe clips are clamped in engagement with the pump-line by means ofthreaded bolts and set-nuts thereon.

It is sometimes necessary to employ a coupling-block for connecting thesections of a broken pump-line. I have here shown two forms, one ofwhich is shown at 26 and consists of two plates having coincidentchannels to receive the ends of the pump-line sections and have passedtransversely through them a clamping-bolt 27. Obviously by tighteningthe nut on this clamping-bolt the two plates may be drawn closely intoconnection with the pump-line sections. The other device (shown at 27*)consists of a coupling longitudinally slitted from end to end, the outerportions of said ends being tapered and provided with a screw-thread tobe engaged by a tapered nut, so that by turning these nuts on saidhalves the clamping ends will be brought into close connection with thepump-line sections.

In connection with the pump-line plates 18 and 19 I employ large clips28, consisting of parts having perforated shank portions through whichfastening-bolts may be passed to secure the same to the pump-lineplates, and the entire portion of this clip is longitudinally slitted,so that it may be pressed against the pump-line with a clamping action.The outer portion of this slitted end is tapered and provided with ascrew-thread adapted to be engaged by a clamping-nut, also tapered onits inner side. (See the upper left-hand side of Fig. 2.)

Referring to the modification shown in Fig. 6, it will be seen that inlieu of the mastergear 9 I have employed a band-wheel 29, the inner endsof the spokes of the same being clamped between ring-plates 30 31. Theplate 31 is provided at its center with a flange or hub portion adaptedto engage with the sleeve 7, and the plate 30 has an opening in itscenter sufficiently large to engage around said hub portion. When inposition, the two plates may be secured by bolts or otherwise. On theplate 30 is rigidly secured eccentrically to the axis of the sleeve 7 aring-plate 32, somewhat similar to the ring-plate 14, heretoforedescribed. On this ring-plate 32 is mounted a pump-line plate 33, whichcarries antifrictionrollers 34, which in this example of my improvementare shown as engaging the outer surface of the ring-plate 32. Above thispumprod-actuating mechanism is another eccentric pump-rod-actuatingmechanism similar to the upper one shown in Fig. 2. In this example Ihave also shown a winding-drum 35 as secured to the upper portion of thesleeve 7,

by means of which a pump-line may be drawn inward when desired todisengage it or to attach one to a clip.

The operation for drawing in the rod consists in attaching arope orother similar connection to the pump-line and then giving the rope aturn or two around the drum. Then by setting the drum in rotation theline may be drawn inward.

In Figs. 1 and 2 I have shown another means of drawing a line inwardwhen it is desired to connect the same to a clip or detach it therefrom.This means consists of two rods 35 36, having their adjacent endsscrew-threaded and engaged by the interior thread of a sleeve or nut 37.Of course these threads must extend in opposite directions, that is, onea lefthand thread and the other a right-hand thread. To the centralportion of the sleeve or nut 37 is attached a hand-wheel 38, by means ofwhich the sleeve or nut may be turned. The inner end of the rod-section35 is provided witha hook adapted to engage around the post or shaft 6or around the sleeve 7, as occasion may require. Adjustably mounted onthe rod-section 36 is a dog 39, adapted to engage with the outer side ofa coupling-block 27*, as plainly shown in the drawings. The rodsection,36 extends loosely through an opening in the dog 39, and the parts maybe secured as adjusted by means of a pin passing through perforations insaid dog and rod-section.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
